What it does

Larger injectors are needed when an engine makes more power, together with a tune. Air and fuel parts decide how well the engine breathes and how cleanly it runs, so the right part restores smooth running and can support more power on a modified engine.

Installation & tips

  • Use new O-rings and lubricate them lightly with clean oil before installation.
  • Fuel filter: Protects new injectors.
  • Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
